Pregnancy-associated SCAD is a severe condition characterized by high-risk anatomy, poor response to PCI, and a high risk of recurrent ischemic events.
Pregnancy-associated spontaneous coronary artery dissection is commonly associated with left anterior descending, left main, and multivessel involvement, which leads to a high incidence of reduced ejection fraction, and life-threatening maternal and fetal complications. Percutaneous coronary intervention is associated with low success rate and high likelihood of complications, and coronary artery bypass surgery is often required. Recurrent ischemic events because of persistent or new spontaneous coronary artery dissection are common during long-term follow-up.
